ETC 74LS05

54LS05/DM54LS05/DM74LS05 Hex Inverters
with Open-Collector Outputs
General Description
Pull-Up Resistor Equations
This device contains six independent gates each of which
performs the logic INVERT function. The open-collector outputs require external pull-up resistors for proper logical operation.

Absolute Maximum Ratings (Note)
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
Note: The ‘‘Absolute Maximum Ratings’’ are those values
beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The
parametric values defined in the ‘‘Electrical Characteristics’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
